Pearl groove, by ball, different riding position realizes that angle is sheared therebetween.This design easily causes ball abrasion, so as to
Inside and outside initiation on fixture ball groove stress concentration, fixture is caused to destroy, durability is not high.
(2) connection of traditional moulds and forcing press is unsatisfactory, mostly the design without horizontal displacement device or only exists
Instrument upper end sets horizontal displacement device, and when experiment can not ensure that pressure position direction and forcing press central axes are coaxial, effect
Not as good as the instrument of both ends setting horizontal displacement device, horizontal displacement caused by causing instrument tip frictional force due to loading is offset
Effect situations such as not optimizing, unbalance loading may be caused, so as to reduce the accuracy of experiment.
(3) traditional moulds employ the combination of the parts such as bearing, angle adjustment wedge, plane bearing, realize rock change
The major function of angle shearing, but in design three be it is isolated place, each part is needed successively as loose mail stacks during experiment,
Mold also needs to be bundled in above forcing press using iron wire in experiment, and when use is very inconvenient and cumbersome.
(4) for set of rock shearing mold pair, shearing inclination is unique, is needed since shearing inclination changes using not
Same mold is secondary and causes test operation cumbersome.In addition, rock shearing mold pair easily occur in use edge gnaw it is bad
Phenomenon, thereby results in mold global failure, and frequent renewal part increases experimentation cost.
To sum up for rock angle shearing die, consume fast there is complicated, partial component in varying degrees and become
The problems such as angle complicated mechanism.To realize accuracy, the ease for operation of the shearing of rock angle, a kind of novel positioning slide formula is developed
Rock angle shearing die, it is meaningful.
